Policymakers need to know if the structure of competition and the degree of banking market concentration change the incidence of financial crises. Previous studies have not always come to clear conclusions. We use a new dataset of 19 countries where we include capital adequacy and house price growth as factors affecting crisis incidence, and we find a positive role for bank concentration in reducing incidence. In addition, we look at New Industrial Economics indicators of market structure and find that increased market power also reduces crisis incidence. We conclude that attempts to increase competition in banking, although welcome for welfare reasons, should be accompanied by increases in capital standards.

银行集中度和金融危机

政策制定者需要了解竞争结构和银行市场集中度是否会改变金融危机的发生率。以前的研究并不总是得出明确的结论。我们使用了 19 个国家的新数据集，其中我们将资本充足率和房价增长作为影响危机发生率的因素，我们发现银行集中度在降低发生率方面具有积极作用。此外，我们研究了市场结构的新工业经济学指标，发现市场力量的增加也降低了危机的发生率。我们得出的结论是，尽管出于福利原因而受到欢迎，但增加银行业竞争的尝试应该伴随着资本标准的提高。
